mozilla websites

I know this might not be the correct place to post but ALL MOZILLA sites have me locked out. I CANNOT log in nor register as a new user because my ONE AND ONLY email is called "incorrect" both as a credential or as a new user. The same is true of my password. Is there a fix to this? Or way to contact MOZILLA another way? I want to post inf for their users. Please send answer to my email here. Thanks.
